Summary
This case study highlights a successful combined aortic root repair and coronary artery bypass surgery in a patient with poor left ventricular function. The procedure significantly improved cardiac function and quality of life.
Area of Science:
- Cardiovascular Surgery
- Cardiac Surgery Techniques
- Aortic Root Surgery
Background:
- Patient presented with aortic root aneurysm, aortic regurgitation, and severe coronary artery disease.
- Pre-existing poor left ventricular function complicated surgical risk.
- Previous history of rectal cancer surgery.
Observation:
- Concomitant aortic root remodeling and coronary artery bypass grafting were performed.
- Myocardial protection utilized intermittent retrograde cold blood cardioplegia and leukocyte-depleted terminal blood cardioplegia.
- The patient had a 1-year uneventful follow-up post-surgery.
Findings:
- Postoperative angiography revealed significant improvement in left ventricular function, with ejection fraction increasing from 24% to 46%.
- The patient remained free of cardiac events during the 1-year follow-up period.
- The described surgical technique demonstrated efficacy in improving cardiac performance.
Implications:
- This surgical approach may offer significant benefits for patients with severely depressed left ventricular function undergoing aortic root repair and bypass.
- Improved postoperative quality of life is a key consideration for this patient population.
- Further studies are warranted to validate these findings in a larger cohort.
